def delete(self,request,pk):
product = get_object_or_404(Product, pk=pk)
if product.orderitems.count() > 0:
return Response({‘error’: ‘Product cannot be deleted because it is associated with an order item.’}, status=status.HTTP_405_METHOD_NOT_ALLOWED)
product.delete()
return Response(status=status.HTTP_204_NO_CONTENT)
